SAZ-4500D

The SAZ-4500D is the largest and most powerful amplifier produced by Sundown Audio. It features a newly tooled extra wide casing to contain the massive circuit board and dual pairs of 1/0 power/ground terminals. If you need the most possible Sundown Audio power then look no further than the SAZ-4500D! This is a serious SPL competition amplifier featuring EIGHT power supply transformers and THIRTY TWO power supply MOSFETs.

This amplifier can draw HUGE amounts of current - in excess of 500 amps - you MUST have a very large high output alternator (250-300 or more amps) AND 3-4 Group-31 batteries to power this amplifier (we suggest XS Power D3100s or Stinger SP2150s). Without such electrical system upgrades the warranty is void as they are a *requirement* to run an amplifier this large. We suggest installation only by professional and/or experienced installers for this amplifier.
